Best Milling filter for Stihl MS 660

[Rough Hewn]

Does Stihl really expect people to buy a new HD2 filter every month??? I thought you were supposed to blow them out and wash them once in a blue moon?

That’s why I asked if he’d read it…
Hd2 filters will work even when completely caked in dust.
There are tests on YouTube where guys half bury different saws in sawdust, and wait to see which fail first.

Determining if an air filter is effective is simple, tach a saw running with a brand new air filter to pre determined RPM, put on a soiled filter and register the RPM, replace with the aftermarket one and measure again. if the revs drop when the air filter is fitted, it is restrictive.

 

I actually tached a MS460 with and without its HD2 filter as the owner wanted to fit a Maxiflow and the result was that the cleaned used HD2 filter had very little restriction on the airflow compared to no air filter being fitted. You can tell from this that the HD2 air filter is working pretty well.

How did the maxiflow perform?

I would assume Andy that it was not any better than no filter at all unless it is a turbo in disguise.

Still would be good to know if the maxiflow (sounds like a pantie liner  ) performed better or worse than a new HD2.

I didn't have it, he was adding it later so it tuned it close to max with no air filter in preparation.

My personal opinion is hat they are significantly over priced for a lump of foam and some plastic.

I don't do milling but a pair of tights makes a good sock that will keep your filter clean and have the advantage of making the saw run a little more rich thus stopping it overheating in the longer cuts.

BTW.....You don't wear the stockings, you put a piece of tights around the air filter!! I know the Monty Python song....no smoke......... just saying!

That sounds effective.

I have 3 of the Stihl felt bands that fit around HS2 and change them, rotating the 3, so can do 3 big cuts before I stop and airline the HS2 and the 3 bands ready for the next 3 cuts.

Not sure this is as good as anything anyone else does but the HS2 stays pretty clean.

I think trig likes the idea of tights on his saws 🤭 Bit of a fetish
